Are you connecting to InfoBright via PostgreSQL ODBC?
If so, you may want to try making the ODBC customizations
to the datasource (writing to the *.tds file) or to the connection (*.tdc).
You may want to try modifying (setting to value = 'Yes') the following capability:
or even try different combinations of capabilities
in the CAP_ODBC_METADATA_SUPRESS_... section.
Hope it could help a bit.
